Application filed April 3, 1920.

To (ZZZ whom it may concern:

Be it known that l, HERMAN N. MATZEN, a citizen of the United Statesresiding at Cleveland Heights, in the county of Guyahoga and State ofOhio, have invented a certain new and useful improvement in Pipes, ofwhich the following is a full, clear,

and exact description, reference being had to the accompanying drawings.

This invention relates to pipes and has for its general object toproduce a pipe which will be and remain dry in use and whichnevertheless is capable of easy clean- One of the greatest objections toordinary pipes is the flooding of the mouth of the smoker with liquidcontaining nicotine and an infusion of the tobacco within the bowl ofthe pipe. This flooding is due to the fact that in the ordinary pipe,saliva from the mouth of the smoker enters the bowl, at least duringsome of the positions of the pipe, and in a subsequent position of thepipe enters the mouth. To prevent this action, various forms of trapshave been introduced between the mouth-piece and the bowl; but thesetraps render the cleaning of the smoke passage ditlicult and materiallyincrease the cost of the pipe.

By my invention, a continuous smoke duct extends from the mouthpiece tothe bowl, making the cleaning operation simple, and this duct extendsupwardly from the mouthpiece to the bowl in all ordinary positions ofthe head of the smoker. Thus no moisture from the mouth can enter thebowl or even the smoke passage in the stem; and the pipe will always bedry and its passage may be cleaned from time to time by the use of theordinary cleaning wire or implement. M In thedrawings forming parthereof, Fig. 1 represents a perspective view of a pipe constructed inaccordance with my invention; Fig. 2 a central lon itudinal sectionalview of the same illustrating the position in which the pipe issupported in the mouth of a smoker; Fig. 3 a plan view of the pipe; andFig. 4 a sectional view corresponding to the line 4-4 of Fig. 3.

Describing the parts by reference characters, 1 denotes the bowl of thepipe, the

said bowl having a stem projection 2 provided with a threaded recess 3for the threaded projection 4 on the stem 5. The mouthpiece 6 and theportion of the stem adjacent thereto are widened transversely,

and wide upwardly and downwardly pro et-ting shoulders 'i' and 8 areinterposed between the body of the stern and the mouthpiece, theshoulder 8 being slightly in advance of the shoulder 7, that is, beinginterposed between the shoulder 7 and the bowl.

The stem 5 extends downwardly from the connection 4 to the mouthpiece,and a con tinuous smoke duct extends downwardlv from the bowl-and saidconnection to the mouthpiece in all ordinary positions of the pipe whenin use.

With the normal arrangement of upper and lower teeth, the inner surfacesor edges of the upper teeth of the smoker will natu rally and readilyengage the shoulder 7 and the outer surfaces or edges of the lower teethwill naturally and readily engage the face 8 of the shoulder 8. Thisenables the smoker naturally to hold the pipe with the duct 9 extendingupwardly toward the bowl. As the head is inclined downwardly the naturaltendency of the smoker is to close the teeth more firmly on the stem atthe same time thrusting forwardly with the lower jaw. This results intilting the pipe upwardly to compensate for the downward inclination ofthe head. In fact, because of this natural tendency of the smoker tothrust the lower jaw forwardly when the head is inclined downwardly, Ihave found it to be unnecessary to provide all pipes with the shoulder8, the lower teeth sliding forwardly on the bottom of the mouthpiece asthe head is thus inclined and the action of the upper and lower teethtilting the pipe upwardly so that the smoke passage 9 will always extendupwardly to the bowl.

'The shoulders 7 and 8 are made of considerable width, as shown, so asto permit each to be engaged by at least two teeth of the smoker. Theposition of the shoulder 8 may be varied with respect to the deliveryend of the passage 9 to accommodate variations in theset of the lowerjaws of difierent smokers. Because of the continuity of the smokepassage 9 it may be cleaned as occasion may demand by any of theordinary flexible cleaners.

Having thus described my invention, what I claim is 1. A pipe comprisinga bowl, a stem and a mouthpiece having a continuous smoke passagewayextending upwardly from the mouthpiece to the bowl, and means on saidmouthpiece arranged to be engaged natu 1 0 shoulder shoulder whereby theupper teeth of a smoker will hook against the front of the uppershoulder and the lower teeth will naturally bear against the rear of thelower shoulder to cause the pipe bowl to be elevated naturally by theclosing of the teeth against said mouthpiece.

In testimony whereof, I hereunto aflix my signature.

HERMAN N. MATZEN.
